Sorry for the very late response.
AXE10 solutions support a very flexible TSS – Trunk and Signalling Subsystem – module that can be configured to support numerous signalling (e.g. R2, ISUP, UK-NUP, etc..).
Depending on the local signalling system a customisation maybe required for proprietary SS7 signalling stacks.
